In order to answer the above question, it is necessary to determine whether a given person is covered by the Act on assistance to Ukrainian citizens or under temporary protection. For this purpose, see points 1 and 13 of our guide The Law on Assistance to Ukrainian Citizens:
If you are a citizen of Ukraine covered by the Act on Assistance to Ukrainian Citizens, by law, you are entitled to healthcare on the same terms as Polish citizens. This means that, according to the law, you do not have to meet additional conditions, e.g. an appropriate stamp in your passport.
It results directly from Article 37 Paragraph 1 Law of 12 March 2022 on assistance to Ukrainian citizens in connection with an armed conflict in the territory of that state (Journal of Laws, item 583, as amended).
In practice, however, clinics may require confirmation of crossing the border within this period or a PESEL number with an appropriate note.
If for some reason, despite meeting the conditions set out in the Act, you cannot obtain a PESEL number with an appropriate note and you have a problem with receiving healthcare, contact us or another organization that provides legal assistance.
It is also worth remembering that private entities, as a gesture of solidarity, undertook to provide free medical assistance to people from Ukraine (for example: https://medycynaprywatna.pl/grupa-lux-med-z-pakietem-pomoc-dla-ukrainy/)
If you are not covered by this act, but you are covered by temporary protection, then you are also entitled to health care, but to a more limited extent. The Head of the Office for Foreigners is responsible for providing it, and this is where you should report for medical assistance (ul. Taborowa 33 in Warsaw).
